제품 설명
Non- halogen Fire Retardant Chemicals Ammonium Polyphosphate Flame Retardant APP
Description of Product
Molecular formula : (NH4PO3)n n>1000
CAS No.: 68333-79-9
EINECS No.: 269-789-9
HS CODE: 2835.3990
Model No.: TF-201
Ammonium polyphosphate (Phase II) is a non-halogen flame retardant. It acts as a flame retardant by the intumescence mechanism. When APP-II is exposed to fire or heat, it decomposes to polymeric phosphate acid and ammonia. The polyphosphoric acid reacts with hydroxyl groups to form a nonstable phosphate ester. Following dehydration of the phosphate ester, a carbon foam is built upon the surface and acts as an insulation layer.
